Gluten-free diet craze

Kelly Courson has been gluten-free since 1996. She says that stripping gluten from her diet solved all of her gastro-intestinal problems.

"In two weeks it was like a miracle cure," explained Courson.

Gluten is a protein found in wheat, barley and rye. It’s used in everything from soups and sauces to breads and pastas, cakes and cookies – mostly processed foods.

When Courson was first diagnosed, there weren’t many gluten-free products on the market.

"You had to drive a long ways to get it,” explained Courson. “Like it wasn't at your local grocery store."

Today, gluten-free products are everywhere. Cookies, popcorn, chips, bagels and cupcakes are available at most markets. Even some restaurants, like Lilit Café in Bethesda, Maryland are offering gluten-free menus.

And Hollywood A-listers like Gwenyth Paltrow, Lady Gaga and Kim Kardashian are boasting about losing weight with a gluten-free diet. But for everyone following this latest trend, watch out.

"In actuality there's a lot of processed foods, sweets, that are gluten-free that actually have a high amount of fat and sugar," explained Carol Casco, a Clinical Dietician at Washington Hospital Center.
